The labor source cement plant is one of building materials
profession large-scale backbone enterprises, the existing 4 belts
afterheat boiler violates the law the spatial cement rotary kiln.
# 1, # 2 kilns specifications are Phi 3.7 □N 3.3 m * 70 m, # 3
kilns specifications are Phi 3.3 m * 58 m, # 4 kilns specifications
are Phi 4.0 m * 70 m; Annual production cement > 1 million t.
The chamotte ?fever is in the cement production process
center link, ?burns in the system to the chamotte the main hot
working parameter: The kiln tail temperature, the kiln fast, the
negative pressure and so on carries on the accurate examination and
reasonably controls, is helpful to the guarantee cement production
process unit performance full display and the long-term safe handling,
thus realization high yield and high quality low consumption
production. My factory uses the collection survey and the
management from August, 2001 is body D R 18 C non- paper recording
instrument examination # 1, # on 2 kilns tails warm, the negative
pressure, the rotational speed and # 4 kilns 料仓 the warehouse
heavy and so on seven parameters, the effect is good.
1 D R 18 C non- paper recording instrument synopsis
D R 18 C non- paper recording instrument (hereafter
refers to as D the R recording instrument) is the non- paper recording
instrument third generation product, it has used the width angle of
view, the width temperature, 640 * 480 lattices liquid crystal display
record curve; F L A S H R A M high-speed storage data recording;
High reliable floppy disk data backup three new technologies.
Moreover this demonstration meter also has the scene operation
to demonstrate and manages the operation to demonstrate two kind of
outputs contact surfaces, may separately meet the different need.
D the R recording instrument altogether has 16 entire
intelligences analog input channel, the volume small, the power loss
is low, may directly receive the thermal resistance, the
thermo-element and the standard signal input. Therefore,
produces regarding the kiln tail temperature after the thermo-element
examination the voltage signal (m V), may the direct input to D in the
R recording instrument channel; But kiln rotational speed,
negative pressure and 料仓 after the warehouse heavy signal only
must transform 4 ~ 20 m the A standard signal then to deliver D the R
recording instrument in the channel.
2 D R recording instrument scene operation and demonstration
Installs in # 1, # 2 kilns operation control console D
the R recording instrument, through to kiln tail temperature, kiln
fast, negative pressure and warehouse heavy examination, or is carries
on the result by the value way by the curve way on its liquid crystal
display monitor the real time display. The scene altogether is
equipped with eight kind of demonstrations pictures, main picture can
simultaneously demonstrate the examination seven parameters. #
1, # 2 kilns heads looked 火工 acts according to the host picture
the demonstration result as well as from already many years 观火
experience, but promptly adjusts the kiln the operating condition.
If □□ in the host picture demonstrated the examination the
tail has heated high or low when □□ must promptly adjust spurts the
coal amount the size □□ thus to guarantee produces the quality well,
the output is high, consumes the low chamotte. Establishes in
addition in the host picture has each kind of function button, but
conveniently carries on for example: The picture choice, the
channel choice, the historic record recall as well as the data saves
operation and so on plate
3 D the R recording instrument in manages on the computer the
operation demonstration
D in the R recording instrument has data analysis
software to use in to manage the operation. This software is
uses V B development development and may install on the office
management computer. Its function establishes as □□ the
reading according to the floppy disk, the demonstration choice
(numeral demonstrated and current capacity accumulation
demonstration), the printing, puts shrinks and the measuring range.
After enters this software, then assigns out in the scene
duplication data plate the data, and demonstrated on the screen by
digital or the curve way, or prints from the printer, does for
long-term preserved or the management production use.
4 uses effects
Although D the R recording instrument is only to the
field data examination, positive governing production, but its
examination result real is reliable, thus for kiln looked 火工
guaranteed the kiln throughout was at the good operating condition to
provide the prompt reliable information and the basis, had achieved
uses effect which the closed-loop control system energy band came.
After nearly two years use, its use superiority and its effect
as follows:
□□ (1) tail warm control stable, had according to may look up,
basically ceases Gao Weiwen to operate the phenomenon. Installs
D in front of the R recording instrument, time the shift relief tail
warm superelevation, the responsibility is unclear, after installs D
the R recording instrument, not only may accurately determine when
shift relief tail warm, provides the basis for the inspection;
Moreover has provided the precise data to the tail warm control,
had guaranteed the craft system effective execution, the big reduction
brings to completion the circle phenomenon.
□□ (2) to negative pressure control effective surveillance
function. In the row of air blower rotation positive governing
kiln 通风? in installs D before the R recording instrument,
negative pressure control ineffective monitor method. If
individually looked 火工 secretly enlarges a row of wind favor from
already class's in output enhancement, but stably has the quite
tremendous negative influence to the entire kiln, after is easy to
create ties the circle phenomenon. After installs D the R
recording instrument, may carry on the effective monitor to the
negative pressure, to rotary kiln steady running positive function.
□□ (3) to kiln rotational speed monitor. My factory # 1,
# 2 kilns request in the kiln transmission aspect not to have to
surpass 1 r/ m i n, surpasses this rotation rotary kiln to be able to
appear not steadily revolves, to 窑衬 is influential. Since
uses D the R recording instrument, may fast carry on the monitoring as
necessary to the kiln, ceased the ultra kiln fast phenomenon.
□□ (4) lives 料仓 the heavy effective monitor to the rotary
kiln. Since has used D the R recording instrument for to live
料仓 the heavy monitor, lives heavily 料仓 continuously controls
above 12 t, ceased the low storehouse position phenomenon, stably
plays to in the kiln material the decision role.
After the nearly 2 years use, we thought D the R recording
instrument the survey accuracy, the demonstration reading as well as
the data record and so on all make one quite be satisfied, moreover
basically reached higher authorities to exempt the maintenance
condition. Moreover, because this non- paper recording
instrument has used the advanced microcomputer technology, achieved
the versatile analog input, the volume small, the power loss low, the
versatility broad, the independence strong, the picture color bright,
the reading direct-viewing, the reflection keen reliable, the data
preservation, has recalled extremely is all convenient, was the
collection survey and the management is a body better equipment,
therefore, we thought this recording instrument not only to be allowed
to use in on the rotary kiln, moreover also was allowed to use in the
cement enterprise other equipment parameters examinations, also might
use in other professions.
